feat(capsule): 录音胶囊样式可选（流光 Siri / Openless 默认）+ 修复 beta 构建破坏

[appergb]

User description

目标

设置 → 录音与输入在「录音胶囊」显示开关下新增「胶囊样式」下拉，用户可自行选择：

• 流光 Siri 风格（默认，SiriGL 光效舞台，现状不变）
• Openless 默认风格（恢复 1.3.14 经典毛玻璃药丸：音量条 + 取消/确认按钮 + thinking 扫光 + 翻译徽章）

兼容性

• 新增偏好 capsuleStyle（'siri' 默认 / 'classic'），旧配置缺失字段自动回落 'siri'（Rust/TS 双侧 serde default）
• 胶囊样式随 capsule:state payload 下发（capsuleStyle 字段），设置里切换后下一次录音即生效，无新权限需求
• 选区润色轻量提示不受样式影响

评审修复（commit 3）

1. 经典药丸按钮可点：胶囊窗口自纯光效舞台时代起永久 set_ignore_cursor_events(true)（鼠标穿透），✕/✓ 按钮实际收不到点击。现在主线程闭包按「classic && visible && 非选区润色 && 录音/转写/润色中」关闭穿透（按钮可点；代价是窗口底部 460×180 区域在会话进行中拦截点击——与 1.3.x 经典胶囊同款取舍，终态 toast 立即恢复穿透），值不变时不重复调用系统 API。
2. 音频线程零偏好锁：emit_capsule 在音频回调线程 ~30Hz 被调，原先直接 prefs.get()（整份克隆 + 偏好锁被 set() 跨磁盘 I/O 持有）。改为 Inner 上 AtomicU8 样式缓存，主线程闭包每帧从 prefs 同步（与 show_capsule 同源），音频线程只读原子。
3. 恢复「录音胶囊」行 desc 文案（beta 原有）。
4. Capsule.tsx 注释同步按样式区分的退出动画常量。

附加修复（独立 commit）

beta HEAD 存在构建破坏：SelectionPolishSection 仍传快捷键重构（e12c8dcc）已删除的 alignRecordButton / modifierPresets，tsc 必失败。本 PR 顺带适配新 API（value 可空 + onReset 恢复默认快捷键，等价旧「启用」按钮），恢复 beta 可构建状态。

测试

• cargo test --manifest-path src-tauri/Cargo.toml：865 passed, 0 failed（注：overlay_elevenlabs_cancel_finishes_idle_without_error_capsule 为 beta 既有 flaky——macOS 非阻塞 socket WouldBlock 时序竞态，未改代码的 base 同样间歇失败，与本文无关）
• npm run build（tsc + vite）：通过
• npm test：15 个前端契约测试全部通过
• 手动预览：?style=classic（浏览器胶囊 dev 预览）

证据路径

• 功能：设置页截图 / 两种胶囊形态录屏（手动 macOS 验证中）

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Possible Issue The set_ignore_cursor_events(true) restore logic only runs inside the deferred (entry-frame) main-thread closure, next to the window.show handling. Mid-session state transitions (Recording → Transcribing → Polishing → Done/Cancelled/Error) go through the non-deferred immediate emit path, so the capsule window keeps ignore_cursor_events=false during the whole ~1.5s terminal toast, swallowing clicks aimed at the app below in the 460×180 area — contrary to the PR description's stated intent that the terminal toast immediately restores mouse passthrough. Passthrough is only restored on the next session's entry frame. This assumes defer_capsule_emit is only set when the window is shown from hidden, as the surrounding comments indicate; if the terminal-state emit is also deferred, this issue would not trigger. let interactive = classic_style && visible && !selection_polish && matches!( state, CapsuleState::Recording | CapsuleState::Transcribing | CapsuleState::Polishing ); let want_passthrough = !interactive; if inner_for_main .capsule_cursor_passthrough .swap(want_passthrough, Ordering::SeqCst) != want_passthrough { if let Err(e) = window.set_ignore_cursor_events(want_passthrough) { log::warn!("[capsule] set_ignore_cursor_events failed: {e}"); } }
